;9 claims.

In my prior patents,"1,-81 3,615 and 1,813,616, dated July 7, 1931, Ihave described and'broadly claimed a novel shaving brush whichenablesone to heat the water passing to the bristles. In my present invention,I have'devised novel means to effect/the automatic ignition of the fuel,

and the automatic extinguishing of the-flame when the water has beenheated to a predetermined temperature- Further objects of the inventionare to simplify the construction so that the shaving'brush can beeconomically manufactured; to construct and coordinate the parts sothatthere will not be a fire hazard and the construction will fool-proofin use; and to provide forth'ehousing of the igniter unit to preventaccidents whenthe fuel is being poured into the fuel chamber? 7 With theabove and other objects in view'as will hereinafter clearly appear, myinvention 0 comprehends a'novel automatically ignited-and extinguishedhot water shaving brush. 7

Other novel features of construction and advantage will hereinafterappear in the detailed description and the appended claims. 25 For thepurpose of illustrating theinvention, I have shown in the accompanyingdrawing a typical embodiment of it, which in'practice ,-will givesatisfactory and reliable resultsl Itis, lfiiowever, to be understoodthat the various instru- 30 mentalities of which my invention consistscan be variously arranged and organized, and my inven tion is notlimited to the exact arrangement and organization of theseinstrumentalities as herein set forth. i 35 Figure 1 is a side elevationpartly broken'away of an automatically ignited and extinguished hotwater shaving brush, embodying my invention.

which receives the container I.

Figure 2 is a side elevation, partly'brokenaway V Similar numeralsindicate corresponding parts. I Referring to the drawing:

I designates a cup shaped container, closed at its bottom and open atits top and having withinit an'annulus of absorbent or wick'mate- 5 rial2. 3 is an open ended tube secured in any desired manner within thecontainer l, for example by spot welding at the bottom, and this tubeforms a housing for an igniting unit 4 of well known construction andpurchasable in the '1 open market. Beneath the unit is a spring 5 havingits lower end preferably fixed, and this spring tends to move theigniting unit upwardly. The upper end of the igniting unit has fixed toit a novel flanged cover 6 closing the upper end '13 of the tube 3 whenthe parts are in closed position. A rod 1 fixed to the cover projectsupwardly to contact with the concave bottom 8 of a water tank9. Toprevent condensation in the tube 3 it is provided with an atmosphericport H opening through the bottom of a lower cap I l The outer peripheryof this cap is preferably knurled and at its upper portion it is ofreduced diameter and threaded as at l2.

The tank has depending from it a sleeve 13 in telescopic relationshipwith the container l and provided with rows of air ports [4, l5 and IS,

the ports in the different 'rows being preferably in staggered relation,and the two upper rows being smaller in diameter than the lowermost row.The bottom of the tank 9 is grooved near its ,outer periphery as at H toreceive a sealing gasket I 8 of asbestos or other suitable material withwhich the upper end of the container I will contact when the parts arein closed position as will be understood from Figure 3.

The water tank 9 converges upwardly and terminates in a threadedenlargement I9 to receive the threaded apertured base 20 in'which thebristles 2| are 40 securely set. A valve 22 having a handle 23 may beemployed if desired to control the communication between the tank 9 andthe bristles 2|.

The tank 9 is preferably provided with an v annular recess 24 to receivethe thermostatic members 25, any desired number of which may beemployed, three of such members being shown. Each of these membersis oflei-metallic thermostaticmaterial having one end fixed to the wall ofthe tank and their outer ends free to move inwardly when the temperatureof the water in the tank 9 has reached a predetermined degree to releasetheir pressure against the inner wall of an outer sleeve 26 and permitit todrop sufl l v a:

ficiently to close the air ports l6, l and I4 and thus extinguish theflame. The lower end of the sleeve 26 is internally threaded tocooperate with the threads [2 or the cap ll.

The embodiment shown in Figure 5 is similar I to that shown in the otherfigures except that the V the spring 5 and screws it to the cap I'l.

' 21 engaging the thermostat will prevent the sleeve 26 isinwardly'curved to grasping portion for the user.

The operation will now be apparent to those skilled in this art and'isas follows:

provide a better base 26 is'unscrewed and the Water tank Alcohol 9filled to a desired amount with water. or other ignitable fuel is'placedin the container I to saturate the Wick Zand the sleeves l3 and 26 aremoved into the-position seen in Figure 3 with the outer sleeve 26screwedto the cap H. The shaving brush is now ready for repeatedoperations. The user unscrews the sleeve 26and the spring 5 raises theigniting unit 4 and the inner sleeve i3 so that the openings l4, l5 and[6 are uncovered, and the sleeve 26 is raised into the position seen inFigure 2. The air entering the ports causes the igniting unit to glowand the alcohol is ignited, thus heating the water in the tank 9. Theouter sleeve 26 is retained inits raised position bythe thermostaticmembers 25 contacting with its inner face until the water reaches apredetermined temperature, whereupon the members 25 will move inwardlyto release the outer sleeve which will drop sufficiently toclose theports I4, l5 and i6. This causes the burner to be extinguished as theflow of'air to the burner is cut off. The user then presses the outersleeve downwardly against the pressure of The operator can now use-theshaving brush in the conventional manner, the hot water passing to thebristles. If the valve 22 is employed, such valve is of course opened.,7 a

When the outer sleeve 26'is raised, the stop sleeve 26 being detachedfrom the sleeve I3.

will slide over the thermostat.

The atmospheric vent l6 prevents condensation in the tube 3, so that theigniting unit' l will'ignite the fuel as soon as the sleeve i3 raisessufiiciently to uncover the air ports. The upper row of ports I 5 and I6prevent the flame from the burner fiar-, ing outthrough such ports.

The bottom cap II has openings 28 to the atmosphere. trolled by a valve29 of any desired character.

As shown, a rotary ported valve is mounted on the bettorn cap so thatthe valve may be turned to open or close the port ID as may be desired.
